What is the appropriate cold tire pressure in summer?

[DiWilliam]

Summer cold tire pressure between 2.2~2.5 is normal, relevant information is as follows: Cold tire pressure: The generally recommended cold tire pressure is 2.5, which results in lower fuel consumption, and when driving at high speeds, the tire pressure can be controlled within the safe range of 3.0. Tire pressure: In fact, different vehicle models have different requirements for tire pressure, including different maximum and minimum limits for tire pressure. The same tire installed on different vehicle models will have different pressure requirements, so the optimal tire pressure is not a fixed value but varies depending on the vehicle model. The standard tire pressure value for each vehicle model is indicated in the user manual, on the inside of the fuel tank cap, or below the B-pillar on the passenger side. Although manufacturers provide the optimal tire pressure value, it should also be adjusted according to temperature changes. In summer, when temperatures are higher, it is recommended to reduce the tire pressure by 0.1~0.2, while in winter, when temperatures are lower, it is recommended to increase the tire pressure by 0.1~0.2.
